Hi Ryan,

Any of the content you assign will always be available to students---there's not currently a way to remove their access to the assignment after the due date. The Scores tab in your class will always show the highest score for each student, even if that assignment attempt was after the due date.

If you need to identify students' scores at the time of the due date (or identify late submissions), then I suggest downloading the assignment CSV report for each individual assignment. To do this, go to the Assignments --> Manage tab in your class and click on the numbers under the Completed column for the assignment you wish to view. You should then see a Download CSV button in the top right of the popup. This report will show you each student's best score overall, best score at the due date, number of attempts, and the time of the most recent attempt.

Editing the due date for an assignment will change the due date for all students---there is not currently a way to modify the due date for individual students. One workaround is to create a copy of the assignment with the new due date and only select the student who needs the extension in the Students dropdown. However, this will cause multiple versions of the assignment to show up in your Scores and Manage pages, which can be quite confusing. Instead, I suggest re-downloading the individual assignment CSV reports as needed.

I hope this helps! Please let me know if you have any additional questions!
